                                    The addition of alkyl isocyanoacetates and isocyanoacetonitrile to alpha,beta-unsaturated sulfones affords a convenient and broad access to pyrroles with unusual substitution patterns (see Scheme 2). The alpha,beta-unsaturated sulfones required as starting materials are easily obtained from different olefines.
